Hi William

[root@local xilinx_sysace]# cat /proc/partitions

I want to know wether the zeroes in the entry  are due to problem in flash file system format or due to the driver.

The zeros indicate there have been no I/O transactions. Can you write to the device or partition it using fdisk? Any kernel messages after loading the driver?

After doing some i/o transaction, i got the following output in /proc/partitions.  thanks william.

It looks fine now.

Am able to do fdisk and it shows the partition.

root@local xilinx_sysace]# fdisk /dev/xsysace

Command (m for help): p

Disk /dev/xsysace: 32 MB, 32112640 bytes
4 heads, 32 sectors/track, 490 cylinders
Units = cylinders of 128 * 512 = 65536 bytes

Command (m for help):q

root@local xilinx_sysace]#

As of now i am not able to mount the flash.
The flash is formatted to FAT16 in windows with only one partition.
Can i mount it in linux.? 
Got this doubt after reading the article: http://www.ussg.iu.edu/hypermail/linux/kernel/0404.0/0056.html

Thanks
